Phase 2A

Phase 2A: The Next Phase of MSD's Wet Weather Plan

Phase 2A is the next series, or phase, of wet weather projects required by MSD's Consent Decree to help reduce sewer overflows into local streams and rivers.

Phase 2A was expected to start in 2020, but has not yet been approved by the U.S. EPA.

The U.S. EPA is expected to either approve Hamilton County's Phase 2A plan or decline to approve it and provide comments. If that occurs, the City of Cincinnati and Hamilton County can revise the plan within 60 days or commence dispute resolution.

Background:

In summer 2019, the City of Cincinnati and Hamilton County submitted separate proposed plans for Phase 2A to the U.S. EPA. The City's plan included 73 projects over 10 years and was estimated at about $800 million. The County's plan included 28 wet weather projects over 5 years and was estimated at $450 million. The U.S. EPA rejected both plans and proposed its own 10-year schedule, which includes more projects and is significantly more expensive.

In fall 2019, the U.S. EPA asked MSD to evaluate its Phase 2A plan. MSD submitted a validation report in January 2020, which evaluates the U.S. EPA's plan in terms of cost, engineering, project implementation, and constructability.

On May 12, 2020, Judge Michael Barrett ruled in favor of a pending motion from Hamilton County related to the plan. The judge, who presides over the U.S. District Court in the Southern District of Ohio, Western Division, confirmed the County's motion that its Phase 2A plan should be the plan considered by the U.S. EPA.
